WATER-HEATING APPLIANCE FOR GAS-STOVES AND THE LIKE.

Specification of Letters Patent.

Patented Mar. 14, rate.

Application filed May 25, 1915. Serial No. 30,332.

To all whom it may concern:

Be it known that I, ABRAHAM M. ZIM- MERS, a citizen of the UnitedStates, residing at Baltimore city, State of Maryland, have inventedcertain new and useful Improvements in W'atenHeating Appliances forGas-Stoves and the like, of which the following is a specification.

This invention relates to domestic water heaters which are heated by agas burner, and its object is to provide a water heater in the nature ofan attachment to an ordinary gas-stove, a heating coil being providedwhich is so associated with the burner that it does not interfere withthe use of the stove for cooking purposes.

The invention also has for its object to provide an attachment of thekind stated which can be readily applied to any ordinary gas-stove, nochanges in the structure of the stove, or the burners thereof, beingnecessary.

The above stated objects are attained by means of a novel combinationand arrangement of parts to be hereinafter described and claimed,reference being had to the accompanying drawing, in which- Figure 1 is aplan View of a fragment of a gas-stove showing the application of theinvention thereto, the utensil-supporting grates above the burners beingremoved; Fig. 2 is an enlarged section on the line 2-2 of Fig. on theline 3-3 of Fig. 1.

Referring specifically to the drawing, 5 denotes the top of a gas-stoveof ordinary construction having the usual burners 6, with gratings 7above the latter on which the cooking utensils are supported.

Between the burners 6 and the gratings 7 are mounted water-heating coils8 which are connected in series, and have an inlet connection 9, and anoutlet connection 10 to a tank or other suitable reservoir (not shown).The inlet connection has a cleanout valve 11, and the outlet connectionhas a faucet 12 located adjacent to one end of the stove so that asupply of hot water may be conveniently drawn.

Each coil 8 is horizontally positioned above the burner, and the inletis at the center by a vertical pipe extending upward through a centralopening in the bodv of the burner as shown at the center of Fig. 3 ofthe drawing The outlet is at the outer end of the convolutions of thecoil.

1, and Fig. 3 is an enlarged section The drawing shows two burners 6,each provided. with a water-heating coil 8, but it will be understoodthat the number of coils may be varied as desired, and according to thenumber of burners the stove has.

The convolutions of the coils 8 are spaced sufiiciently to allow theflames of the burn ers to pass therebetween, and as the coils arelocated beneath the gratings 7, there is nothing to interfere with theuse of the stove for ordinary cooking purposes.

Each coil 8 is supported above the burner by a spider composed ofradialarms 1% connected by a series of spaced, concentric rings 15, andan outer ring 16 connecting the outer ends of the arms. The outer one ofthe series of rings 15 has an outstanding arm 17 which seats on top ofthe inlet neck 18 of the burner, and is fastened thereto by a clamp 19.The rings 15 seat on top of the burner, as shown in Fig. 3, and theirspacing is such that they do not obstruct the burner orifices. The arms14: have top recesses 20 which form seats for the convolutions of thecoil. The rings 15 rise a suitable distance from the burner, and as thesupporting arms 14 of the coil are at the top of the rings, the coil isspaced from the burner. The outer one of the series of rings 15 has abottom flange 21 which is curved to fit the side of the burner as shownin Fig. 2.

The arrangement of the coils, and the supporting means therefor enablethe attachment to be readily applied to any ordinary gas-stove withoutchanging or modifymg the structure of the stove or the burners thereof.The attachment is also simple and inexpensive, and it can be easilyinstalled.

I claim:

1. The combination with a gas-stove burner; of a spider mounted on theburner, and a water-heating coil supported on the spider above theburner, said spider comprising radial arms having top seats for theconvolutions of the coil, and spaced concentric rings connecting thearms, and means for attaching the spider to the burner.

2. The combination with a gas-stove burner; of a water-heating coilmounted above the burner, and a support'for the coil, said supportcomprising a series of concentric rings seating on top of the burner andspaced apart, radial arms connecting the rings at the top thereof, saidarms havcoil, said Copies of this patent may be obtained for five centseach, by addressingthe Washington, D. C.

burner; of a Water heating coil mounted above the burner, a series ofspaced, concentric rings'mounted on top of the burner clear of theorifices thereof, attaching means for the rings, and seats for theconvolutions of the coil carried by the rings, said seats being spacedfrom the burner.

In testimony whereof I afliX my signature in presence of two itnesses.
